I talked to a player and he is going to give me a lift in their ship but I cant find it and dont know how to enter it. I looked in the scanner section but that showed no ships. could someone please help me. in getting to it and telling me how to enter it.

It's possible that he's still on his way to your location. Best is to contact him again and tell him your exact location or get his location, if he's already in the city.
If you're then at the same location of the ship, click on the "Enter" button in your travel screen, then select the ship you want to enter.
